The model utility content

The purpose of this utility model is: design a kind of water level automatic generator tool device, not only be not subjected to the impact of river levee dam rivers size but also can effectively solve the problem that prior art exists.

Realize that technical solution adopted in the utility model is: this device by cylindrical guide rod, cylindrical drum, cylinder barrel shaped water wheel axle, float, water wheels, large belt wheel, link bar and generator forms, guide rod is fixed in two rectangle grooves at curve bath two ends, river bed perpendicular to horizontal plane, water wheel axle two ends and cylindrical drum are tightly connected, float and cylindrical drum are tightly connected, the water wheels two ends connect large belt wheel through bearing housing on water wheel axle, linking bar is connected with cylindrical drum, generator with link bar and be connected, on generator, small pulley is connected with large belt wheel through driving belt.

For this device is worked when water level just changes, and concentrated flow increases the impact force to water wheels, allow cylindrical drum move up and down along guide rod, make and allow water wheel axle 3 all the time on the water surface, at the cylindrical drum hypomere, float is set, float is truncated rectangular pyramids shape, wherein two side symmetries, congruences are rectangle, two other side is symmetrical, parallel, congruence is trapezoidal, cylindrical drum is vertically passed symmetry, parallel, congruent trapezoidal bi-side and float and is formed airtight cavity, and is symmetrical arranged, forms " eight " word mouth at water wheels two ends and collect current.

In order to reduce gravity and when the rotating frictional force of water wheels in water, and make water wheels when water level just changes, also can work, water wheels are arranged to be comprised of buoyant closed cavity blade and circular shaft cylinder, reach the floor that support and connection are arranged between blade in blade, blade and floor are connected to the bulk strength that increases water wheels on the circular shaft cylinder.

Good effect of the present utility model is: simple in structure, cheap, easy manufacturing, safe and reliable, energy transformation ratio is high, do not need huge fund to build dykes and dams, can be contained in big or small river waterflow and generate electricity, also can be used for the tidewater generating, and also can work when water level just changes, not only in general area, particularly in the poverty-stricken area, the mountain area easily promotes the use of.
